Miniature rose plant named `POULann`

ABSTRACT

A rose plant of the miniature class, a sport of the variety POULvic, having a different flower color from its parent.

The present invention relates to a new and distinct variety of roseplant of the miniature class which was discovered by us as a mutation ofthe variety POULvic, U.S. Plant Pat. No. 8,012.

This variety is unique and distinct from its parent variety, POULvic,principally in its flower color. Instead of having petals that are ofRed Group 45C color, the petals are Purple-Red Group 58C on their uppersides and Purple-Red Group 55B on their reverse sides.

Asexual reproduction of this new variety by softwood cuttings, asperformed at Somis, Calif., and Fredensborg, Denmark, shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
